一、前言我厂全套设备均由日本提供,属七十年代设备。因此,在硅钢片的生产过程中,带卷的长度测量是必不可少的,在日本国内相应的厂,对硅钢片带卷的长度测量,使用了数字测长仪而提供给我厂的是三套机械计数式测长仪,它用测长轮在钢带上滚动,将位移量转换成数字量的一种机械计数器,由于测长轮直接与钢带接触,磨损很大,误差是很显然的,若安装不理想,测长轮容易脱落,而被钢带带走,圈入钢圈中。影响产品质量。为了适应现代化生产的需要,我们根据厂有关部门的要求,参考了有关长度测量的资料,试制了“Scc—78型数字测长仪”(仪表外貌见图1)。
I. Introduction I plant a full set of equipment provided by Japan, is a seventies equipment. Therefore, in the production of silicon steel sheet, coil length measurement is essential, the corresponding factory in Japan, the length of the silicon steel sheet coil measurement, the use of digital length measuring instrument provided to our plant is Three sets of mechanical counting length measuring instrument, which uses the measuring wheel rolling on the strip, the displacement is converted into a digital amount of a mechanical counter, because the measuring wheel in direct contact with the strip, wear a lot, the error is very Obviously, if the installation is not satisfactory, the measuring wheel is easy to fall off and is taken away by the steel strip, and it is circled into the steel ring. Affect product quality. In order to meet the needs of modern production, according to the requirements of the relevant departments of the factory, with reference to the information on the length measurement, trial production of “Scc-78 digital length measuring instrument” (appearance of the instrument shown in Figure 1).
